Sat, December 24th, 2022	Persistent Slabs	Wind Slabs	The avalanche danger is MODERATE above 1000′ today. It is possible for a person to trigger an avalanche on a layer of facets buried 2-4′ deep. Wind slabs 2-3′ deep in areas exposed to strong NE winds are also possible for human triggering and most likely at upper elevations. Below 1000′ the avalanche danger is LOW. SEWARD/LOST [Read More]
Fri, December 23rd, 2022	Persistent Slabs		The avalanche danger is MODERATE above 1000′. It is possible for a person to trigger a large avalanche 2-4′ deep on weak, faceted snow surrounding the crust that was buried just before Thanksgiving. The areas with the most concerning snowpack are the mountains around Girdwood and towards the south end of Turnagain Pass. The danger is LOW below 1000′. [Read More]
Thu, December 22nd, 2022	Wind Slabs	Persistent Slabs	A MODERATE avalanche danger remains above 1,000′. New wind slab avalanches could be found and triggered in the higher elevations due to increasing easterly winds over the past 24 hours. These could be 1-2′ deep and forming near ridgelines. Watch for active wind loading. Additionally, triggering a larger slab avalanche that breaks in weak snow 2-4′ [Read More]
Wed, December 21st, 2022	Wind Slabs	Persistent Slabs	A MODERATE avalanche danger exists above 1,000′.

Mon, December 19th, 2022	Persistent Slabs		The avalanche danger is MODERATE at all elevations. There is a weak layer of snow buried 2-4′ deep that makes it possible for a person to trigger a large avalanche. Persistent problems like this are difficult to assess, and the only way to avoid the problem is to stay on low-angle terrain. PLACER/LYNX/JOHNSON PASS: We have very limited [Read More]
Sun, December 18th, 2022	Persistent Slabs		The avalanche danger is at the high end of the MODERATE scale at elevations above 1,000′. Triggering an unmanageable avalanche 1.5-3 feet deep that breaks in buried weak layers is possible. These could be triggered from the side or bottom of a slope, or after several people have been on the slope. It’s a tricky [Read More]
Sat, December 17th, 2022	Persistent Slabs		The avalanche danger is CONSIDERABLE above 1000′ today. Based on new reports yesterday, large human triggered avalanches 2-3′ deep on a weak layer of sugary faceted snow are possible today. Remote triggered avalanches are also a concern, which means you can trigger an avalanche from flat terrain and have it release on steeper terrain above, to [Read More]
Fri, December 16th, 2022	Wind Slabs		The avalanche danger is MODERATE at elevations above 1,000′. The snowfall and winds have moved out of the Turnagain forecast zone and our main avalanche issue will be triggering a lingering wind slab avalanche. Wind slabs could be up to 2′ deep and will be found on windloaded slopes and in cross-loaded gullies. Additionally, sluffs [Read More]
